I have the latest version of Thunderbird (91.2.1). When I open an email, I get the "Remote Content was Hidden" banner, which is fine (that is what I want). It gives me the option to "Show Remote Content". I click on that. When I click on it, the content briefly (for about half a second) shows the remote content then the email goes completely blank and the address bar shows: chrome://conversations/content/stub.html?urls=imap-message%3A%2F%2F<redacted content>%40<redacted content>%2FINBOX%234501 By the way, when I open ANY email I get that URL in the address bar. Is that correct? Randomly, the "show remote content" option still displays - sometimes it does, sometimes it doesn't. When I click on that, it finally shows my email with the remote content. The address bar still displays the above URL. I redacted the part of the URL that shows my email address. If I close and reopen the email, the remote content displays. When the "show remote content" bar doesn't continue to display I have no choice but to close the email and open it again. Randomly, when I reopen the email, it is still blank AND there is no "Show Remote Content" bar. Through trial and error, I learned there is a little icon on the right that has a tool tip that says "Show content in a new tab". When I click that, it randomly shows my email and the remote content. Sometimes, though, the email content is still blank. Instead, it displays the message: "We're sorry, but we can't display this conversation, because the messages have been moved or deleted." I close the email and reopen it. It is still blank, but when I click the "Show message in new tab" icon, it show the email the the remote content. Is that how it supposed to work or is this a random bug? I have a feeling this is not how it supposed to work. Just FYI, I disabled all of my addons so they don't interfere with anything. disabling the addons doesn't help. Thanks
